    sand filter sizing question

    Hi, I am upgrading my filter and my local poolman is suggesting the following. I have an Intex 15' x 48' round pool, and it holds about 5000 gallons of water. I just want to make sure he is not selling me what he has left over at the end of the season....

    3/4 hp pump and a 18" sand filter. He said it would take 100lbs of sand. Is it too big or small for my pool.

    Thanks....Bill

    sand filter sizing question

    Filter wise you can't really get to big. With that filter you will probably only backwash 2-3 times a year. Some will say the pump may be to big, go with 1/2hp or 2 speed etc, however my pool is only slighty bigger and I have 1hp and have no complaints at all, it's the best thing I've done for the pool since going bbb!

    100lbs sand filter is fine.
